HEAT-INSULATOR FOR VESSEL-HANDLES.

SPECIFICATION forming part of Letters Patent No. 772,099, dated October 11, 1904.

Application filed November 9, 1903. Renewed July 27, 1904. erial No. 218,307. (No model.)

To all whom it may concern:

Be it known that I, EVERETT D. HOLLEY, a

' citizen of the United States, residing at Forestville, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Heat-Insulators for Vessel-Handles, of which the following is a specification.

The invention relates to improvements in heat-insulators for vessel-handles; and the objects of the invention are simplicity and economy in construction and efliciency in use.

In the accompanying drawings, Figure 1 is a side elevation of two of the insulators together with a portion of a vessel and a handle with which the said insulators are connected. Fig. 2 is a sectional view of one of the said insulators and portions of the handle on the line- 0; (0 of Fig. 1. Fig. 3 is an end view of one part of the insulator. Fig. A is an end view of the companion part of the insulator. Fig. 5 is a transverse section of the insulator with all parts excepting the screw-stem of an oval instead of a round form in transverse section or end View. r

The insulators are formed of two companion parts. One part consists of a centering stud or stump 6, a flange 7, recessed on one side, a screw-stem 8, and an insulating-washer 9, the said stud, flange, and stem being of metal and rigid with each other, practically the same when finished as if formed of one piece of metal. The said flange 7 is recessed upon that side from which the screw-stem 8 projects. The insulating-washer 9 is of vulcanite or other non-conductor of heat and is placed over this stem 8 and within the recess of the flange 7, as shown in Figs. 2 and 3. The other or companion part of the insulator consists of a nut 10, fitted to be screwed onto the screw-stem 8, an insulating tube or sleeve 11, surrounding the said nut, andan attaching outer tube or sleeve 12, of metal, on the outside of the said insulating-tube. The nut 10 is provided with a small flange or head 13 to prevent it from passing end wise through the insulatingtube and attaching outer tube or sleeve.

Two handle connections 14 of any desired socket;

design are secured to the side of the vessel A by solder or otherwise, each having in their outer ends a socket 15 for receiving one part of the insulator, while thehandle-body 16 has in its ends similar sockets 17 for receiving the other part of the insulators. As shown, the part of the insulator that bears the attaching outer tube or sleeve 12 is fitted to the socket 15 in the handle connections 14.

After assembling the nut 10, insulator-tube l1, and outer attaching tube or sleeve 12, as shown in Fig. 4, they are forced in the socket 15 of the handle connection before the companion part of the insulator is screwed into the nut. They should be inserted with the flanged end of the nut toward the bottom of the socket and with the outer end of the said sleeve about flush with the outer end of the If it projects a little, it will do no harm, as it will when the companionpart is attached seat itself in the insulating-washer 9. It will be noticed that the outer ends of the sleeve 12 and socket let are now exposed, so that they may be secured by soldering the outer surface of the said sleeve tothe inner surface of the socket. This can readily be done by any one skilled in soldering. The solder can readily be worked in from the outer end, especially if the seam is left a little open to facilitate thus working in the solder. The companion part, including the insulating-washer9, may now be connected therewith by screwing the screw-stem 8 into the nut 10 and turning it up hard enough to form a firm and rigid connection. The diameter of the handle connection should be a little less than that of the recess in the side of the flange 7, so that it will have no contact with the said flange. The handle-body can now be applied with the stumps 6, received in the sockets 17 in the ends of the said handle-body and with the ends of the said handle-body abutting the broad side of the said flange, as shown. The parts may then be secured by solder in the usual manner.

In Fig.- 5 there isshown the same mechanical construction, only the nut 10*, insulating tube or sleeve 11, attaching outer tube or sleeve 12, and the recessed flange 7 are of an oval form in transverse section or end view instead of the round form shown in the preceding figures. The section in Fig. 5 extends transversely through the screw-stem and surrounding parts without cutting the flange 7, which is shown in the distance. The attaching outer sleeve of one part of the insulator is completely insulated from the companion part, whereby the handle-body when attached, as described, is perfectly insulated from the vessel. the insulating material is all practically concealed from sight when the flange is recessed, as shown. While I prefer to employ a headed nut and screw-stem for convenience of first soldering the attaching outer tube or sleeve within the handle connection, it may be here noted that the screw-stem 8 and headed nut 10 taken together constitute a metal core within the insulating-tube for supporting and securing the attaching outer tube 12;

The centering stump or stud 6 is a convenience in locating that part of the insulator on the ends of the handle-body and also no doubt facilitates soldering the parts together, although the principal seam for receiving the solder is between the broad side of the flange 7 and confronting end of the handle-body 16.

It is apparent that some changes from the specific construction herein disclosed may be made, and therefore I do not wish to be understood as limiting myself to the precise form of construction shown and described, but desire the liberty to make such changes in working my invention as may fairly come within the spirit and scope of the same.

At the same time I claim as my invention 1. A heat-insulator for handles of vessels consisting of a flange, a central metal core projecting from one side of the said flange, an insulating-washer extending outwardly from the said core and resting on the broad side of the said flange, an insulating-tube surrounding the said metal core and an attaching outer tube mounted on the said insulating-tube and held thereon by the said metal core, the said attaching-tube and flange being adapted to be secured to a handle connection and body, substantially as described.

2. A heat-insulator for handles of vessels consisting of a flange, a central screw-stem and nut projecting from one broad side of the said flange, an insulating-washer resting on the broad side of the said flange, an insulating-tube surrounding the said nut and an attaching outer tube firmly held on the outer side of the said insulating-tube with its end insulated from the said flange by the said insulatingwasher.

3. A heat-insulator for handles consisting of a flange recessed on one of its broad sides, a central screw-stem projecting from the said recessed side and a centering stump projecting from its other side, an insulating-washer surrounding the said stem and resting in the recessed side of the said flange, a nut on the said stem, an insulating-sleeve surrounding the said nut, and an attaching-sleeve mounted on the outer side of the said insulating-tube.
